What happened

当source为doris表，有如下一下记录时

INSERT INTO `` VALUES (2, 202231, 176, '0', NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, 198009.3600, 37780.8500, NULL, 738305.4300, 499126.9500, 4511, 948, NULL, 13017, 9824, 3.2094, 43.8948, 39.8532, NULL, 56.7186, 50.8069, '2022-07-28 06:02:20');

doris -> mysql 会空指针

What you expected to happen

可能是在数据类型转换的时候，没有做空值处理
